In older adults, diet and physical activity are among the most important behaviours that influence health. The Mediterranean Dietary Pattern has been related to longevity and can benefit physical function in older adults. The present study aims to quantify the association of adherence to a Mediterranean Dietary Pattern with physical functioning through by handgrip strength, as well as, with sedentary behaviour based on sitting time, in a sample of older adults.
A cross-sectional study was conducted in 1,491 older adults ≥ 65 years old. The adherence or non-adherence to a Mediterranean Dietary Pattern was assessed using the previously validated and translated 14 item questionnaire, the PREDIMED (Prevención com Dieta Mediterránea). Handgrip strength was measured with a Jamar Dynamometer. Sitting time per day was used as an indicator of sedentary behaviour. Multinomial logistic regressions were performed to quantify the association of adherence to a Mediterranean Dietary Pattern with handgrip strength and sitting time.
Compared to participants who adhered to a Mediterranean Dietary Pattern, those who did not adhere to this diet have a significantly higher adjusted odds ratio for low handgrip strength [adjusted odds ratio: 1.50; 95% confidence interval: 1.09-2.05], as well as for longer sitting time [adjusted odds ratio: 1.43; 95% confidence interval: 1.04-1.96].
In older adults, the non-adherence to a Mediterranean Dietary Pattern was associated with both lower values of handgrip strength and longer sitting time.
在老年人中，饮食和身体活动是影响健康的最重要行为之一。地中海饮食模式与长寿有关，并且可以使老年人的身体功能受益。本研究旨在通过握力来量化遵守地中海饮食模式与身体机能的关系，并根据久坐时间来量化与久坐行为的关系，研究对象为老年人样本。
进行了一项横断面研究，共纳入 1491 名年龄≥65 岁的老年人。使用经过验证和翻译的 14 项问卷 PREDIMED（地中海饮食预防）评估地中海饮食模式的遵守或不遵守情况。握力使用 Jamar 测力计进行测量。每天的久坐时间用作久坐行为的指标。采用多项逻辑回归来量化遵守地中海饮食模式与握力和久坐时间之间的关联。
与遵守地中海饮食模式的参与者相比，不遵守这种饮食的参与者握力较弱的调整后优势比显著更高[调整后优势比：1.50；95%置信区间：1.09-2.05]，并且久坐时间更长[调整后优势比：1.43；95%置信区间：1.04-1.96]。
在老年人中，不遵守地中海饮食模式与握力值较低和久坐时间较长有关。
